Synthesis, Structure, and Properties of 2D Lanthanide(III) Coordination Polymers Constructed from Cyclotriphosphazene-Functionlized Hexacarboxylate Ligand
The design and synthesis of novel lanthanide-based coordination polymers (Ln-CPs) from flexible organic ligands is still attractive and challenging. In this work, two isostructural Ln-CPs with a unique 2D network, namely, [Ln<sub>2</sub>(H<sub>3</sub>L)<sub>2</sub>(DMF)]]<sub>n</sub> (Ln = Dy for <b>1</b>, Tb for <b>2</b>) based on a flexible polycarboxylic acid ligand hexakis(4-carboxylato-phenoxy)cyclotriphosphazene (H<sub>6</sub>L), have been solvothermally synthesized and structurally characterized. Significantly, it is the first observation of polycarboxylic acid ligands participating in coordination in the construction of coordination polymers in the form of semi-deprotonation. Magnetic measurements showed the presence of field-induced slow magnetic relaxation in complex <b>1</b>. The luminescence property of <b>2</b> had been studied in the solid state at room temperature.
